Combining these medications may reduce therapeutic effects or increase the risk of side effects. Avoid prolonged exposure to strong sunlight or ultraviolet light during treatment.

If you experience redness, itching, increased skin sensitivity to sunlight while taking this medication, stop taking it immediately and consult an expert. Also consult an expert if neurological symptoms such as fatigue, anxiety, drowsiness, and restlessness or gastrointestinal disturbances occur. In case of overdose, the skin may become sensitive to sunlight, so it is important to protect the skin from sunlight for 1-2 weeks after taking it. Reduce outdoor time and use products with high sunblock indices to protect the skin. This medication can activate enzymes that breakdown other drugs in the liver, which may lower the blood concentrations of other medications. Therefore, when taken with cardiac glycosides, bronchodilators, antiarrhythmics, anticonvulsants, or sedative-hypnotics, the effects may be diminished, and careful observation is needed when starting or stopping treatment. It may also reduce the effectiveness of oral contraceptives, potentially resulting in breakthrough bleeding, so caution is required.
